Looks like you would require a 90mm fan for a plane that size.
For bungee launch you could use a 16 cell motor (750W) like the mega 22/20/3.
With retracts at 6lbs wt then a 25-30 cell motor in a 90mm fan like Mega 22/30/3 would do the trick.
Other Hacker or Kontronics motors would work also but usually at double the price!!
Of course I am bias towareds the Mega range have a look at my website www.gcmdesigns.co.uk
Also remember the airframe should be biult very light for EDF to get the performance.
For 90mm fans I always aim for 25-30 oz/sq foot with very strong high lift low drag wing
